MIG Welding Wire for Steel

Join steel together with this welding wire.

ER70S-2—ER70S-2 wire is good for welding over rust and mill scale. It is made from a blend that helps remove contaminants and imperfections from the weld pool.

ER70S-3—ER70S-3 wire is good for welding carbon steel in general fabrication applications. It has a low silicon content, so you can powder coat your welds.

ER70S-6—ER70S-6 wire is good for welding dirty, oily, and rusty steel. You can also use it to join misaligned pieces together. It creates X-ray quality welds without air pockets for a smoother and more uniform welding bead than standard welding wire. Its high silicon content allows it to flow easily when melted, so it spreads out to fill in the space between two pieces of your weld before hardening.

ER308LSi—ER308LSi rods are for 304 stainless steel. They have a higher silicon content than ER308L rods, so they flow more easily when melted and fill in more of the space between the two pieces of your weld. They’re also better where appearance matters because their welds are smoother.

ER309L—ER309L rods join different types of stainless steel. They’re also for use with steel.

ER309LSi—ER309LSi rods are for 309 stainless steel. They have a higher silicon content than ER309L rods, so they flow more easily when melted and fill in more of the space between the two pieces of your weld. They’re also better where appearance matters because their welds are smoother.

ER316L—ER316L rods are for 316 and 316L stainless steel.

ER316LSi—ER316LSi rods are for 316 stainless steel. They have a higher silicon content than ER316L rods, so they flow more easily when melted and fill in more of the space between the two pieces of your weld. They’re also better where appearance matters because their welds are smoother.

ER630—ER630 rods are for 17-4 PH stainless steel.
